Reverse proxy on IIS server

[DenisG]

Hi,

I'm trying to set up a reverse proxy for the blog by following this tutorial : https://developers.hubspot.com/docs/cms/developer-reference/reverse-proxy-support

The domain is configured on Hubspot and "Ready for publishing".

The IIS server is configured to enable proxy. I have defined rewrite rules for www.mydomain.com/en/blog to https://HubID.suffix/en/blog

(and also for /_hcms/*, /hs/*, /hubfs/*, /hs-fs/*​, and /cs/c/* )

The proxy seems to be correct, as it works if I change the rewrite rule to www.google.com for example)

But with the Hubspot URL, this is the page displayed.

The diagnostic page doesn't work too.

I can see the HTTP headers x-hubspot-trust-forwarded-for and x-hs-public-host, but there is also the following ones :

- x-hubspot-notfound: true

- x-hs-reason: domain XXXXX.sites-proxy.hscoscdn10.net does not exist

I don't know what I'm missing. Any help would be greatly appreciated 🙂

Hi @Jaycee_Lewis,

Thanks for the link but it didn't help.

I realised that I was not sending correctly the HTTP headers, now it's ok, but still not working.

I'm seeing a 404 when going to the diagnostics URL https://[myDomain]/_hcms/diagnostics.

Here are the headers from the https://[myDomain]/_hcms/_worker/headers

x-hubspot-trust-forwarded-for: "true"
x-original-url: "/_hcms/_worker/headers"
x-real-ip: "[serverIp]"

When visiting https://www.mydomain.com/en/blog I can see the following Request Headers :

x-hs-reason: domain [www.mydomain.com] does not exist

x-hubspot-correlation-id: 479250b3-8597-49f3-a49a-50bdb42de334

x-hubspot-notfound: true

which means that the x-hs-public-host header is correctly configured right ?

So I don't know what's missing here.

The domain status is now "Connected to reverse proxy", so configuration looks ok, but pages are still "not available".
